Chicken Fajita Pasta

A creamy, cheesy chicken fajita pasta that brings together sizzling bell peppers, tender spiced chicken, and a velvety sauce that clings to every noodle.

Why This Recipe Works:

• Searing the bell peppers separately prevents them from releasing excess moisture into the cream sauce, keeping it thick.
• Using starchy pasta water helps emulsify the fat from the cheese and cream, preventing a greasy, split sauce.
• Tossing the pasta directly in the pan allows the starch gelatinization to help the sauce cling to every noodle.

I still remember the humid Tuesday evening in my cramped college apartment when I tried to make fajitas and pasta at the same time. My tiny stove only had two working burners, and the chaos that ensued was a tad clumsy, to say the least.

The result was a watery, broken mess.

Whenever I crave bold Tex-Mex flavors but want a break from [Cheesy Rotel Beef Tacos](/2026/07/cheesy-rotel-beef-soft-tortilla.html), this is my go-to.

Most skillet pasta recipes fail because home cooks toss raw bell peppers directly into a simmering cream sauce. This releases excess water, which dilutes the emulsion and leaves you with a sad, puddle-like sauce.

To fix this, you need to sear the peppers first in a screaming-hot cast-iron skillet until they get those beautiful charred edges, then fish them out. Tap your tongs against your hip, take a breath, and let the pan cool slightly before building your sauce. This preserves the texture of the vegetables while keeping the cream thick and velvety.

Using starchy pasta water binds the melted cheese and cream together perfectly.

Let's get cooking.

Ingredients

• 8 oz penne pasta (or use Creamy Chicken Penne style)
• 1 lb chicken breast, sliced into thin strips
• 1 tbsp fajita seasoning (similar to our Cajun Chicken Pasta blend)
• 1 tbsp olive oil
• 1 red bell pepper, sliced
• 1 yellow bell pepper, sliced
• 1 medium yellow onion, sliced
• 3 cloves garlic, minced
• 1 cup heavy cream
• 1/2 cup chicken broth
• 1 cup shredded Monterey Jack cheese
• 1 tsp Diamond Crystal kosher salt
• Fresh cilantro, chopped, for garnish

Directions

1. Cook the penne pasta in a large pot of salted water until al dente, reserving 1/2 cup of pasta water before draining.
2. Heat olive oil in a large skillet over medium-high heat, then toss chicken strips with fajita seasoning and sear until cooked through, about 5-6 minutes.
3. Remove chicken from the skillet, then add the sliced bell peppers and onions to the same pan, searing until tender-crisp with charred edges.
4. Remove the vegetables, reduce heat to medium, add minced garlic, and cook for 30 seconds until fragrant.
5. Pour in the chicken broth and heavy cream, scraping up any browned bits from the bottom of the pan as it comes to a simmer.
6. Stir in the cooked pasta, chicken, seared peppers, and onions, then turn off the heat.
7. Gradually fold in the shredded Monterey Jack cheese and reserved pasta water, stirring constantly until the cheese is melted and the sauce is creamy, then garnish with fresh cilantro.

Notes

• I highly recommend using Diamond Crystal kosher salt; if you only have fine table salt, cut the measurement in half (1 tsp Diamond Crystal = 1/2 tsp table salt) to avoid over-salting.
• The science behind the sauce relies on emulsification; adding starchy pasta water helps bind the fats from the heavy cream and Monterey Jack cheese, preventing the sauce from splitting into a greasy mess.
• Do not add the garlic to a screaming-hot pan immediately after searing the peppers; let the pan cool for a minute first, or the garlic will burn in seconds and turn bitter.
• After a day in the fridge, the pasta will absorb the sauce and become quite dry; reheat it with a splash of milk or chicken broth to restore its velvety texture.

Serving Suggestions

To complete this comforting meal, pair the rich, creamy pasta with bright, refreshing sides that cut through the decadence of the cheese sauce.

• A crisp green salad tossed with a zesty lime vinaigrette.
• Warm, buttery garlic bread for scooping up extra sauce.
• A side of Mexican Street Corn Pasta Salad for a double-pasta feast.
• Freshly sliced avocado or a scoop of homemade guacamole.
• A cold, sparkling lime mocktail to cleanse the palate.

Storage and Reheating

Leftovers are inevitable, but they require care.

Store any remaining pasta in an airtight glass container in the fridge for up to three days. Avoid freezing this dish, as the dairy-based cream sauce will separate and turn grainy upon thawing.

When you are ready to reheat, do not just throw it in the microwave on high. The intense heat will cause the cheese fats to break, leaving you with an oily pool.

Instead, place the pasta in a skillet over low heat and add a splash of milk or chicken broth. Stir gently as it warms to re-emulsify the sauce into its original velvety glory.

Ingredient Substitutes

If you find yourself missing an ingredient, here are some easy swaps that won't ruin your dinner.

1. Chicken Breasts: Swap for boneless, skinless chicken thighs for a juicier bite, or use leftover rotisserie chicken added at the very end.
2. Monterey Jack Cheese: Use mild cheddar, Pepper Jack for an extra kick, or mozzarella if you want an ultra-stretchy cheese pull.
3. Penne Pasta: Any short, ridged pasta like rigatoni, rotini, or cavatappi will work beautifully to catch the sauce.
4. Heavy Cream: You can substitute half-and-half mixed with a teaspoon of cornstarch, though the sauce won't be quite as rich.

I hope this creamy, cheesy skillet brings as much joy to your table as it does to mine. It is proof that even the most chaotic kitchen disasters can eventually turn into something absolutely perfect.
